Name ___________________________ Date ___________________ Class __________________ 6 THE PERIODIC TABLE SECTION 6.1 ORGANIZING THE ELEMENTS (pages 155–160) This section describes the development of the periodic table and explains the periodic law. It also describes the classification of elements into metals, nonmetals, and metalloids. Searching For An Organizing Principle (page 155) 1. How many elements had been identified by the year 1700? ________________ 13 2. What caused the rate of discovery to increase after 1700? Chemists began to use scientific methods to search for elements. 3. What did chemists use to sort elements into groups? Chemists used the properties of elements. Mendeleev’s Periodic Table (page 156) 4. Who was Dmitri Mendeleev? __________________________________________________ Dmitri Mendeleev was a Russian chemist and teacher who developed a periodic table of elements. © Pearson Education, Inc., publishing as Pearson Prentice Hall. All rights reserved. 5. What property did Mendeleev use to organize the elements into a periodic table? Mendeleev arranged the elements in order of increasing atomic mass. 6. Is the following sentence true or false? Mendeleev used his periodic table to predict the properties of undiscovered elements. ______________________ true The Periodic Law (page 157) 7. How are the elements arranged in the modern periodic table? The elements are arranged in order by increasing atomic number. 8. Is the following statement true or false? The periodic law states that when elements are arranged in order of increasing atomic number, there is a periodic repetition of physical and chemical properties. ______________________ true Metals, Nonmetals, and Metalloids (pages 158–160) 9. Explain the color coding of the squares in the periodic table in Figure 6.5. Yellow squares contain metals, blue squares contain nonmetals, green squares contain metalloids.
